The parapharyngeal space.

A series of 73 lesions presenting in the parapharyngeal space is presented. There were 53 (73 per cent) patients with deep lobe parotid benign or malignant tumours, five (7 per cent) patients with tumours of neurogenous origin, seven (9 per cent) patients with abscesses, five (7 per cent) patients with enlarged lymph nodes, two with branchial cysts, and one with a lipoma. The anatomy emphasizes the expansile nature of the space and also the close proximity of vital structures. The importance of the use of combined CAT scan and sialography is discussed in the diagnosis of these patients. The various prognostic factors are mentioned and a description is given of the best way to approach the parapharyngeal space without damaging the facial nerve. With careful planning and preparation of the planned operation, the morbidity of the facial nerve may be considerably reduced.

Factors affecting the extrusion rates of ventilation tubes.

A survey in which 939 ventilation tubes of 8 different patterns were inserted and reviewed (up to a maximum of 2 1/4 years) is analysed. Various factors determining the rate of extrusion are discussed. The Sheehy Collar Button tube remained functional for a longer period than any of the other tubes included in the survey.

The surgical approach to recurrent pleomorphic adenoma of the parotid gland.

This is a retrospective study of 19 patients who were referred to the Department of Otolaryngology, Edinburgh Royal Infirmary with recurrent pleomorphic adenoma of the parotid gland. In the majority of patients, a superficial parotidectomy was performed as primary treatment. Recurrence of the tumour was either due to tumour implantation or inadequate surgical excision. Permanent facial paralysis occurred in three patients after revision parotidectomy. Change from pleomorphic adenoma at first operation to carcinoma in pleomorphic adenoma (malignant mixed tumour) at the second was noted in three patients who are still alive and free of recurrent tumour. Eighteen out of the 19 patients did not have further recurrences after revision parotidectomy. The surgical principles in the prevention of tumour recurrence and revision parotidectomy are discussed.
